摘要/Abstract

摘要： 以浙江千岛湖典型生境片断化区域苦槠(Castanopsis sclerophylla)为材料,研究了水库形成后岛屿化导致的群落生境差异对苦槠AM侵染率的影响以及AM侵染率与根际土壤磷酸酶活性的相关性。结果表明,以生境面积为因子进行单因素方差分析,则不同岛屿生境对苦槠AM侵染率影响差异不显著;但以Pearson相关性分析,AM侵染率与岛屿面积之间呈显著负相关。苦槠根际土壤酸性磷酸酶活性在中岛、大岛与陆地间差异显著,但与AM侵染率之间无显著相关性。

Abstract: A typical area of habitat fragmentation in the Thousand-Island Lake,Zhejiang Province,was selected as subject to study effects of habitat variation as a result of island forming,on arbuscular mycorrhizae infection rate and its correlation with phosphatase activity in the rhizosphere of Castanopsis sclerophylla.Results show that with habitat acreage as the factor in one-way variance analysis(ANOVA) AM infection rate was not significantly different between islands,while in Pearson′s correlation analysis,infection rate was significantly negatively correlated with acreage of an islands.Acid phosphatase activity in the rhizosphere of Castanopsis sclerophylla varied sharply with the size of an island,but was not significantly related to AM infection rate.

Key words: islanding, Castanopsis sclerophylla, arbuscular mycorrhizae, infection rate, phosphatase activity
